North American F-107 Ultra Sabre
North American - F-107 Ultra Sabre - 1956 - США
Страна: США
Год: 1956

Ответом компании «North American» на появление Republic F-105 стал истребитель F-107A. В этой машине была сделана попытка устранить недостатки F-100. А главными отличиями стали регулируемый надфюзеляжный воздухозаборник, киль большой площади и управление по крену с помощью интерцепторов. Были построены три прототипа, однако в серию пошла машина компании «Republic».

North American's Mach 2 fighter-bomber, the F-107A, was cancelled before reaching production, and one aircraft of the three built has been turned over to the National Advisory Committee for Aeronautics for test purposes. The overhead air intake was designed to provide maximum efficiency for the Pratt & Whitney J75 turbojet, which is in the 20,000-lb.s.t. class.

MACH 2 FIGHTER. This drawing gives some indication of what the North American F-107 fighter will look like. In the plan view it resembles the F-100. Side and head-on views show the bifurcated dorsal air intake that feeds the P. & W. J75 turbojet.
NORTH AMERICAN F-107A. One of the world's fastest aircraft is the North American F-107, which is claimed to be capable of a speed of Mach 2 in level flight. Apart from the unusual position of the air intakes the aircraft resembles its predecessor, the F-100, in many ways. In addition to an all-movable horizontal tailplane it has an all-moving fin. A spoiler system for lateral control during high-speed manoeuvres consists of hinged doors on the upper and lower wing skins that control the passage of air over these surfaces. The overhead air duct was designed to provide maximum efficiency for the Pratt & Whitney J75 turbojet engine, which provides more than 20,000 lb. thrust. The F-107 will not be produced as it was dropped in favour of the Republic F-105 Thunderchief. Three prototypes were constructed, and two have been turned over to the National Advisory Committee for Aeronautics (the third is now in the National Air Museum), and will be used for supersonic testing and compilation of research data at Edwards Air Force Base. Studies scheduled include investigating control characteristics of an aeroplane with an all-movable fin, in-flight evaluation of the dorsal air inlets for the engine, and a general analysis of the flying qualities of the F-107 which incorporates many new ideas in control systems. General performance reveals that it flies in the region of Mach 2 in both level and climbing flight and exceeds Mach I in a vertical climb. Maximum air speed is in excess of 1,300 m.p.h.
